Welcome to this Workshop!

First, some basic concepts …..

What is PPPOE?Point-to-Point Protocol over Ethernet or PPPoE, is a Layer II network protocol that usedfor encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is usedmainly with DSL services where individual users connect to a DSL modem over Ethernet.As you know Ethernet networks are packet-based and have no capacity for a connection orcircuit. They also lack basic security features to protect against IP and MAC conflicts androgue DHCP servers, so most Internet providers separate their users traffics to severalVLANs .

Imagine that our Network Topology is:

EoIP Tunnel Ethernet over IP (EoIP) Tunneling is a MikroTik RouterOS protocol that

creates an Ethernet tunnel between two routers on top of an IP connection. The EoIP tunnel may run over IPIP tunnel, PPTP tunnel or any other connections capable of transporting IP.

EOIP tunnels add at least 42 bytes overhead.(8 bytes GRE + 14 bytes Ethernet + 20 bytes IP)

InterVLAN RoutingSome times in addition to the PPPOE Connection you may need to have

Layer III communication between your branches. (for example for managing your devices)

In this case you use InterVLAN Routing…

Let`s go to implementing PPPOE over EoIP TunnelAnd
